Per Sam Ruby, Microsoft has submitted a proposal for distributed extensibility in HTML5, which features the use of namespaces.
The proposal uses reverse DNS names, but other than those ugly sons-of-bitches, it looks promising. There are some issues, including no support for innerHTML on namespaced elements, because they would end up defined as Element, not HTMLUnknownElement, but I don’t think that’s going to be a real problem in the wild. More importantly, I believe the proposal would handle the problems I noted in my last writing, about the valid use of namespaced elements and attributes in SVG. The issue with namespaced elements in SVG isn’t a made-up problem or one that is unlikely to occur: it is a real problem, it will occur in the future, and it does require real solutions. The problem is not going to go away because Ian Hickson clicks ruby shoes together and murmurs “There’s no such thing as namespaces…there’s no such thing as namespaces…” This absolute refusal to acknowledge something that has existed on the web for a decade is, frankly, unconscionable.
I wish I could say that the happy campers of the HTML WG are willing to at least enter into an open and unbiased discussion on the proposal, but I stopped believing in fairy tales, a long time ago. There is contention on this issue (namespaces for distributed extensibility), as noted in the past, in the current discussion, in the HTML WG bug database, related to the new RDFa-in-HTML proposal. Needless to say, the WhatWG members have responded in their typical, open and mature manner.
But here’s some cold, hard reality for Ian et al: this isn’t a proposal from folks like me, who have little say, and no power. This proposal comes from Microsoft. Microsoft, who still maintains a dominant position when it comes to browser use in the world. The HTML5 editor cannot simply ignore the proposal, pretend he doesn’t understand it, or rubber stamp it WONTFIX. Not this time.
